Machine Learning definition:

  1. "Field of study that gives computers the ability to learn without being explicitly programmed." 在没有明确设置的情况下,使计算机具有学习能力的研究领域。
  2. "A computer program is said to learn from experience E with respect to some task T and some performance measure P,if its performance on T,as measured by P,improves with experience E." 一个适当的学习问题定义如下,计算机程序从经验E中学习,解决某一任务T进行某一性能度量P,通过P测定在T上的表现因经验E而提高。

Machine Learning algorithms:

  1. Supervised learning(监督学习)
  2. Unsupervised learning(无监督学习)

Others:Reinforcement learning(强化学习)

Recommender systems(推荐系统)

目前有各种不同类型的机器学习算法,最主要的两类是监督学习和无监督学习,简单的说,监督学习就是我们教会计算机学习某些东西,而在无监督学习中我们让计算机自己学习。
